Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:

I'm in the same situation with my ZX81 at the moment: white screen with no cursor.

Which finally was the damaged part in your case, the ULA or the Z80 ? I think that do you replaced one of them, tested the ZX81 and replaced the other one later it isn't?
